The quest Gold Dust Exchange (http://www.wowhead.com/quest=47/gold-dust-exchange) puts three points, two in the Fargodeep mine and one in the Jangolode mine. Possibly intentional.

Kobolds at both locations drop the dust, so it's probably they're both left in.

As for there being two for one location I'm planning on implementing something that checks for a minimum distance before adding another point to avoid unnecessary duplicates (they're everywhere)

Alright. Would you like me to continue reporting bugs or is this project not very serious.

I'd love it :) Any bugs people submit are definitely appreciated. I want to get things really polished, and I don't intend on stopping any time soon.
Still getting used to the whole "managing a github project" thing though, bear with me.
